UDP does not seem to work (TCP works just fine) for the following:

- Ubuntu 9.04 (jaunty):  Linux xxx 2.6.18.8-linode22 #1 SMP Tue Nov 10 16:12:12 
UTC 2009 i686 GNU/Linux
- cygwin : CYGWIN_NT-5.1 xxx 1.7.7(0.230/5/3) 2010-08-31 09:58 i686 Cygwin

This is for iperf version 3.0-BETA4 (2 Aug 2010) .

Following is the command output(s):

-------------- server ------------
     $ ./iperf3 -s -p 1111        
     -----------------------------------------------------------
     Server listening on 1111
     -----------------------------------------------------------
     Accepted connection from 127.0.0.1, port 42747
     The client has unexpectedly closed the connection.
     -----------------------------------------------------------
     Server listening on 1111
     -----------------------------------------------------------

-------------- client ------------
     $ ./iperf3 -c 127.0.0.1 -p 1111 -u        
     Connecting to host 127.0.0.1, port 1111
